Technical Data Sheet Terocore 1401 CA-25
Two-component structural foam to increase the stiffness, strength, fatigue strength and improving the vibration behavior pumped, room temperature curing
Product Description Terocore 1401 CA-25 is a two component, low expanding, high-strength structural epoxy resin-based foam having high compressive strength and low density. Terocore 1401 CA-25 is free from solvents, isocyanates and PVC. Curing takes place at room temperature by the reaction of A and B component. The reaction can be heated by the Components are accelerated up to 50 ° C. Depending on the geometry and Amount of material, the foam can vary degree. Applications Terocore 1401 CA 25 containing hollow microspheres, reducing its stiffness, strength and duration be increased vibration resistance. Applications include voids, sheets and Structural parts. Terocore 1401 CA-25 can be used for prototypes or as a repair solution of cartridges for the large-scale operation to be processed out of barrels.

Processing
Terocore 1401 CA-25 is located in the cartridges in the ratio 2:1 before (by volume). To Processing is the safety pin from the plug. Subsequently, the unscrew top cap, the stopper removed and attached to the mixer before remote cap screwed back on the thread. (Note: Use only original mixer since otherwise can be assumed for the mixing no warranty!) For applications in cavities or parts of the structure to be reinforced parts are quite or partially filled with Terocore 1401 CA 25th (Note: Terocore 1401 CA-25 is expanding by about 0 - 30%) Where appropriate, a hole with a diameter of 7 - 14 mm are drilled, through which the material may then be introduced. The openings are then simply sealed with tape. Functional openings after filling with Terocore 1401 CA-25 must still be used, by prior introduction of Terocore 1401 CA-25 kept free appropriate action. Optionally it is possible, while the openings expose the curing process before the final curing of the foam. If after removing the required amount Terocore 1401 CA-25 nor material in the cartridges is present, the mixer is removed, cleaned thoroughly and the MaterialauslassΓΆffnungen Safety plug and the cap put back. The remaining material is then possible to are processed by a new mixer is placed.
Curing
The curing process takes place without additional heat from the outside only by chemical Reactions take place at room temperature after the mixing of components A and B. Warning: This reaction can be carried large quantities Terocore 1401 CA-25 to excessive heat lead. The heat generation and thus the curing time and degree of expansion are determined by the Application temperature, and the geometry of the filling body, and the material quantity determined. When surface application in thin layers of heat and degree of expansion are small. When filling large volume of voids in the material to temperatures up to 160 ° C be achieved. The increase in volume is then about 30%. The parts have to be filled may be handled or transported with protective gloves. After about 8 to 24 hours (depending on Temperature, application, and amount of introduced free surface) has cured the material.
Cleaning
Fresh, uncured material should immediately with a dry cloth of the substrates or the cartridge and gun tips are wiped. Remains of Terocore 1401 CA-25 can be removed (eg, benzene) with solvents. In barrel processing systems The filled with mixed material parts are cleaned by rinsing with the A-component. Cured material can only be mechanically removed.
